Frequency — The number of cycles per second. One volt is equal to the difference of potential that would drive one ampere of current against one ohm resistance. It is also used as one theory to explain direction of current flow in a circuit. But all circuits must obey the basic principle of a closed loop. "Basic" spacing is nominal and can change with conditions. Commonly used for filtering out voltage spikes. The electrons flow in one direction only. It is therefore in the interest of anyone involved in electronic circuit design to have the ability to develop filter circuits capable of meeting a given set of specifications. Vars may be considered as either the imaginary part of apparent power, or the power flowing into a reactive load, where voltage and current are specified in volts and amperes. If you put resistors next to a penny, you get an idea of how small they are. Farad — A unit of measure for capacitance. Car batteries are 12 volts. Terms in this set (40) Ampere (A) The unit of measurement of electric current. The inductance is directly proportional to the number of turns in the coil. Electronics is the processing of electrical charges as information. It travels from the power plants to our houses in big cables hung high in the air or buried in the ground.
